1981 D9 high drive

[bobcat ron]

Yup, what the title says, probably the first one I've ever seen yet from 1981, I didn't even know they were made back then.

43,000 hrs, that dozer must have been through hell and back, any offers?

that d9 realy is not that bad after a good bath. it was working at a slag plant in detroit.

That D9L has probably had more money put into than it cost new over the years.
